ber, from the space between said pads, and` from the garment or fabricsbeing pressed any steam, vapor, moisture or water thereon, said4 meansbeing connected to operate conjointly with the device for applying steamto the garment or fabric for the pressing operation. More specificallythe object of the invention isto provide an improved pressing machine`whose lower pressing member is so arranged that the operator can directsteam therefrom upon the garment 0r fabric or can withdraw through saidAmember the steam, vapor or moisture.

A further object of the invention is to pro vide an improved pressingmachine embodying means for applying steam to the garment and means forwithdrawing the steam, vapor and moisture, said. two means beingoperable from the same controlling device, and preferably in such mannerthat either of said means can be rendered eifectiveywhen desired, theother means being simultaneously rendered ineffective.

Further objects of theinvention vare in part obvious and in part willappear more in detail hereinafter.

Referring to the drawings, Figure1 is a side elevation illustrating theapplication of the invention toone form of pressing machine; Fig. 2 is a.plan view, artly 1 n section on the line 2-2, Fig. 1; ig, 3 1s a detailsection on the line 3 3, F1g. 2, showing the steaming valve; Fig. 4 abroken out'plan view of the lower pressing member; ldig.5 is alongitudinal section on the line 5 5, Fig. 4; and Flg. 6 is a crosssection on the line 6-6, Fig. 4.-

, The inventionmay be ap lied to any desired form of pressing mac e,butmthe drawings, for purposes vof illustration, has been shown appliedto a pressing machine of the general orm shown'in my prlor apf.

plication for pressing machine, filedv Aug. ,14, 1916, Serial No.114,794. For clearness of illustration the main parts ofthe machine havebeen shown in dotted lines, the full lines representing the parts moreimmediately concerned in the present invention.

rlhe machine shown comprises a suitable frame 1 supporting the lowerpressing member or bed 2 and having a swingingarm or lever 3 on which islocated the coperating upper pressing member or head 4. Said twopressing members are moved toward and from each other for the pressingoperation by swinging movement of said lever, as will be readilyunderstood.

rlhe lower pressing member, shown in Figs. 4, 5 and 6, comprises ahollow body 5 having an inner steam heating chamber 6 supplied withsteam from pipe 7 circulated through said chamber to the outlet pipe 8.The bed usually has a'slight turning movement on the frame toaccommodate itself to the head, the axis of turning movement in thiscase being the axis of the pipes 7 and 8. Above chamber 6 is ahorizontal wall 9 separating said chamber from a shallow space orchamber10 between wall 9 and a-thin metal plate 11 having a large num ber ofsmall perforations 12 and above which is the padding 13. Chamber 10serves two purposes. First, itis a steam discharge chamber from whichsteam is supplied through the perforated plate and padding to thegarment or fabric lying upon the bed, and, second, it serves as a vacuumchamber through which the steam,

vapor and moisture are withdrawn. For

these purposes it is connected both to a steam supply and to a source ofvacuum.

The chamber 10 shown has 'a number of radiating or diverging ribs 14 tosupport plate 11. The channels between said ribs lead to one or twoopennigs 15 communicating by lateral-passages 16 with apipe 17 connectedto a pipe 18` extending downwardly to a suitable source of suction, suchas the inlet side ofthe centrifugal pump 19 driven by a power source,for example,

the electricmotor 20. In pipe 18 is a suitable valve 21 having a Slidingvalve stem 22 which opens theV valve when pulled outand Vcloses itwhenpushed in. The motor and pump run ,constantly so that whenever valve-21 is open suction Vor vacuum ise'ective 1n and abutting a collar 39 onthe valve stem.

chamber 10 and any steam, vapor or moisture on the garment or in thepads or the space between said pads is -withdrawn through chamber 10 anddischarged through the pump. 23 indicates a pipe or conduitcommunicating by way of the valve 24 with the pipe 18 leading to thecavityv 10. This pipe 23 may communicate with any suitable source ofsteam supply, and in the drawings is shown as communicating with thelive steam space or heating chamber 6. Valve-24 is provided with a rod25 connected to a link 26 which is supported by a stationary rod 27, thevalve 24 bein'g normally held closed by a spring 28.

The operating mechanism for the two valves 21 and 24 is so arranged thateither one may be opened to render either steam or vacuum effective inchamber 10, the arrangement being preferably such that when one valve isopened the other is closed and vice versa. As shown the operatingmechanism comprises a bell crank lever having a foot treadle 29 and anarm 30 connected to a link 31 whose free end has a lateral proj-ection32 surrounding steam valve stem 22 in advance of a collar 33 adjustableon said stem and secured thereon by a set screw 34. Collar 33 carries adepending weight 35, andas the valve stem is horizontal, said weightapplies lateral bending movement to the valve stem suicient to preventthe valve from crawling from any position in which it may be and therebydisturbing its setting.

Link 31 is moved rearwardly (to the left in Fig. 1) by a spring 36 toopen the vacuum valve. When said link is moved in the op .posit'edirection it first closes the vacuum valve and then compresses a spring37 housed in' a chamber 38 of the projection 32 This constructionprovides lost motion between the linkand vacuum valve so that theiir's/t motion of the link may be utilized to close the vacuum valve andits further m0- tion to open the steam valve.

' link 31 which engages. an arm 41 on memhe may do so`by depressing ber26 when the link is pulled forwardly by the bell crank lever. If theoperator desires to apply steam to the padding or garment which closesthe vacuum va ve 21 and opens the .valve 24, thereby permitting thepassage of live steam from the space 6 through the pipe 23, .through thesteam valve 24 to that part of the pipe line 18 which is above the valve21. This valve'21 being-closed at' this' time, the steam rises throughthe pipe 1 8 to the chamber 10 and throu h the padding.,

The construction descri d is simple and i Jcanbe redilyapplied to anyform of pressingmachine..` It puts both the steaming de.-

vice' and vacuum" attachment underthe con-Jl Said steam valve isopened-by a lateral 'projection ing Steam to the Space bers, meansconnecting said chamber to a'- the t'readle 29,

3.
